Father brought printer ink for $126.97 from warehouse stationary, I went back to get a refund and brought online for $83.95

The thing that annoyed me the most was "don't go back to return it because I don't want you to." I pressed for a better argument, but that's all I got.
Question: How do you justify a $43.02 difference?
Answer: Because I don't want you to return it.
So I was like go **** yourself and I just returned it.
